This year had no shortage of romance among the stars. From Justin Timberlake and Jessica Biel saying “I do” under the stars in Southern Italy, to Ryan Reynolds and Blake Lively secretly getting hitched on a sprawling Southern plantation, many buzzed-about celebrity couples found their happily-ever-after in 2012.

Even some of the industry’s most beloved golden girls turned bridal. Natalie Portman tied the knot with her Benjamin Millepied in a traditional Jewish ceremony in Big Sur, Calif., where Anne Hathaway also walked down the aisle at sunset to wed Adam Shulman.

Drew Barrymore vowed for forever with Will Kopleman at her Montecito, Calif. estate, while Carey Mulligan took the plunge with Mumford & Sons musician Marcus Mumford in the countryside of Somerset, England.

But wedded bliss didn’t bless everyone, with many longtime lovers calling it quits in 2012. After almost seven years of marriage, Heidi Klum and Seal announced their separation in January before officially filing for divorce three months later.

Parting ways after five wedded years, Tom Cruise and Katie Holmes — long labeled Tomkat — reached a surprisingly speedy divorce settlement after just 11 days in July, with the actress receiving primary custody of the couple’s six-year-old daughter, Suri.

But not all of Hollywood’s bitter breakups stuck. Back in July, Kristen Stewart was infamously snapped smooching her married Snow White and the Huntsman director Rupert Sanders, seemingly ruining her three-year relationship with Twilight co-star Robert Pattinson. But Twihard broken hearts were soon on the mend, as Stewart and Pattinson were spotted canoodling in Los Angeles, Calif., in October.

Now, as the countdown begins to 2013, look back at this year’s biggest weddings, breakups and makeups.
